We divide 720468 by 20
We're looking to find how many times 20 goes into 720468.

On to step 1:
20 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 20

Step 2:
72 divided by 20 is 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 60 from 72 and we're left with 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 20

Going ahead to step 3:
The number 20 fits into 120 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Deduct 120 from 120 and we're left with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 20

Let's proceed to step 4:
When dividing 4 by 20, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 360.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 20

Step 5:
20 can be fit into 46 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 3602.0
If we subtract 40 from 46, we get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 20

On to step 6:
68 divided by 20 is 3 with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 36023.0
If we subtract 60 from 68, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
20 goes into 80 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 36023.4
If we subtract 80 from 80, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 36023.4
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 36023.4
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 36023.4, and the remainder is 0.0.
